Ideal Control Module Imax Xtra F80 174385

The Ideal 174385 is a control module printed circuit board for Ideal Commercial Imax Xtra appliances. It is the electronic board that runs the appliance's operating sequence, reading inputs from the sensors and switches and driving the fan, pump and ignition stages in the correct order. The board sits at the centre of the control circuit, so a failure here stops the appliance responding to demand.

• The appliance does not start when there is a call for heat, with no fan or pump response.
• Fault or error codes appear on the appliance display and will not clear.
• The appliance locks out repeatedly or at random intervals during a run cycle.
• The display is blank or the control panel is unresponsive.
• Fan, pump or ignition stages run out of sequence, or one stage runs without the others.

• Confirm the appliance model and serial number against the compatibility list before ordering.
• Compare the part number printed on the existing board with 174385, and check for 1779239 on the board label.
• Photograph the wiring, connector positions and DIP or jumper settings on the old board before removal so the replacement can be set up the same way.
• Check the condition of the board's mounting clips and any ribbon or plug connections, as these are disturbed during replacement.
